To all whom' it may concern:

Be it known that I, FORREST SMITH, a citizen 'of the United States, and a' resident of Council Bluffs, in the county ci Pottawattamie and State of Iowa, have invented a new and Im roved J ar-Closure, of which the following 1s a full, clear, and exact descri tion.

The invention relates particularly an improvement in cardboard closures orstolpxo pers for bottles and jars-such, for examp e, as are commonly employed for carrying milk.

The object 4of the invention is to enable the cardboard closures tobe quickly and easily removed by hand without necessitating the use of al tool or instrument of any sort,v and I attain this end by cutting, unchingz or otherwise producing a group otpperforatlons passing completel through the thickness of zo the cardboard an( ,forming a weakened-portion which may be readily broken awayl either in whole or in 'art by ones finger, enabling the under sid)`e of the closure to be reached and permitting it to be easily drawn out of position. The perforations are preferably filled with paratiin or other e uivalent substance, which maintains the c esure hermetic, and after the closure has been broken to remove it the broken mrtion may 3o be pressed hackinto place. and the closure still employed to cover the bottle during the time that milk may remain therein.

Reference is had to the accompanying drawings, which illustrate, as an example.,

the pre erred manner of' carrying out my' invention, in which drawings- Figure l is a plan view ot'v the closure, and Fig. 2 is a'scctional view showing the closure in position on the hottlcorjar.

4o a indicates the cardboard closure, and b indicates the series` of perforations therein. Thesev perforations may he arranged in any way desired. A convenient forni is that of a double hook or letter S, as shown in the drawings. After the, perforations are formed the closure' is covered orimpregmtted with paratlin or its etplivalent, which is allowed to enter the openings b, hermetieally closing the same, as indicated at. e in the drawings.

5o' The closure is 'plat-eden the jar in the I 'usual mannerjand when the closure is to he removed it is'only necessary to press in the 'the closurea second time inserte part of the closure which has been .weakened y the erforations, so that theV finger may f enter be ow theclosure andthe closure lifted out of piace. Milk or other liquid in thejar ma then'be withdrawn in whole' or in part,

an( if it is deslred to replace the closur'e temporarily the part which had been pushed away may be pressed back into (places and 6o.

-into the mouth of thej-ar.

By perforating the caps or closui'eaas4 con'- tradistinguished rom scoring orf otherwise weakeningthem,both sides of the closure are 6 5 left alike and there need be no selection of sides when closing the jars, thus saving time. Further, the perforations passingcompleteiy throughv the stock are not affected lby varia- 1 tions in the thickness of the same, a uniform 7o weakening being secured irrespective of the ossib'ility. of the board of which the closure 1s formed varying in thickness. l

Having thus described the preferred form of my invention, what Ielaim as new,4 and desire to secure by Letters Patent, isv

1. A jarclosure formed of a sheet of lmate-` rial having a series of perforations extending com letely through the sameand forming a ,wea ened portion, fo'r the purpose specified, 8o said perforations being filled with an impervious material.

2. A jar-,closure formed'of a cardboard disk having Aa series of perforations extending completely through it, producing a weakened 8 5 portion, for the pur )ose s ecied, and said pertorations being ti led with an impervious material. f

3. A jar-closure formed of a thin sheet 'of semitlexihle material, such as cardboard, 9o provided with a series of closely-juxtaposed perforations arranged in a line and extending entirely through the said sheet, the perfora# tions allowing the retention of the form of the sheet when theclosure is in use, andy allowing a part of the sheet adjacent to the perforations to be broken away at will to facilitate withdrawing the closure.

4. A jar-closure formed of a thin sheet 'of semitlexihle material, such as cardboard, pri'ivided with a seriesot' ci(iselyjuxtaposed perforatious arranged in aline and extending eutirelv through the said sheet,- the perfora- IOL/ tions allowing the retention ofthe form ofthe l *I sheet w`hent`he closure is in use, an'd allowing` name to this speciffmenti'oxi in the prsence of a. part of th slxeet- :@djacent'tzl thefperlforatwo subscribing witnesses.
